[Morphologic characteristics of HBV markers and products of iron metabolism in liver tissue in patients with hepatitis B virus].

In the histomorphologic analysis of 126 liver biopsies with hepatitis B virus (HBV) infection the authors have met some difficulties in the interpretation of findings of three biopsies which showed the presence of hemosiderine and ferritin deposits in hepatocytes. The lack of cells with the appearance of "ground glass", that is, ground glass hepatocytes which are one of the important features of HBV infection and aberration from the standard features in some histochemical stainings are noticed in all three biopsies. Since only few authors have noticed the same problem, it is possible that these results open new ways in the study of pathogenesis of HBV infection in the liver and its relationship with iron metabolism.

[Effects of urban noise on mental health].

The results of the latest studies on the effects of urban noise on mental health are presented in this paper. Numerous psychiatric symptoms have been frequently noticed in the population of the settlements with a high level of urban noise: fatigue, headaches, tension, anxiety, irritability, bad concentration, insomnia, whith a consequently high consumption of psychotropic medicines. Higher admission rates in psychiatric hospitals have been noticed from noisy areas in comparison with low noise regions. By use of diagnostic psychiatric interviews it has been shown as well, that in sensitive categories of population positive correlation can be expected between the number of persons with mental disorder and the level of environmental noise. Noise annoyance and sleep disturbance, namely shortening or absence of the sleep phase 4 and REM, are the basic negative psychological effects of noise, with an adverse effect on mental health in general.

[Hypertension in patients with post-streptococcal glomerulonephritis].

Sixty two patients with poststreptococcal glomerulonephritis (PSGN), aged 18-22 (mean = 19 +/- 0.5 years) were examined and treated at the Clinic of Nephrology of the M.M.A. from the beginning of 1986 to the end of 1990. Hypertension (diastolic pressure over 13 kPa, that is, 97.5 mmHg) in the acute phase was found in 59 (95.16%) patients, being of milder degree and short-term course. Transient increase of blood pressure required sometimes a short therapy (with furosemide mainly). With normalization of the glomerular filtration rate, withdrawal of edema, and normalization of the plasma volume, the blood pressure has been also normalized in the majority of patients (within 3-5 days). Observing PSGN evolution in the period from 2 to 5 years, hypertension was found in 3 (6.8%) of 44 patients. All three patients had the clear clinical evolution (proteinuria and erythrocyturia) without signs of renal insufficiency. The rebiopsy of the kidneys showed milder morphologic changes which were more manifested compared to the group without hypertension. Hypertension was present in the majority of patients in acute phase of PSGN while it was rarely found during the evolution of the disease and its presence has been poor prognostic sign in evolution since it contributed to development of glomerulosclerosis and later on renal insufficiency.
